Specification Of Letters Patent.

OIL-CUP.

Patented Mar. 1, 1921.

Applictaion filed January 20, 1920. Serial No. 352,810.

T 0 all whom it may concern:

Be it known that I, STEPHEN I. Fn in'rn, a subject of the King ofHungary, reslding at Detroit, county of Wayne, State of Michigan, haveinvented a certain newand useful Improvement in Oil-Cups, of whlch thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to oil cups which are used for the lubrication ofparts of machinery and motor vehicles and the object of the invention isto provide a closure for such oil cups to keep dust and grit out of theoil cu Another object is to provide a closure which will open for theinsertion of the spout of the oil can without the use of the operatorsfingers.

As is well known to those skilled in the art, the operator of anautombbile wlllnot go to any considerable trouble to do 011111 If thework can be done neatly and \Vlfi'l the use of one hand instead of two,it is much more apt to be performed regularly and frequently than ifboth hands have to be,

used and if the user is likely to get his hands oily. My improvedclosure is intended for use particularly with a novel type of oil cupshown in my companion application filed January 20, 1920, Serial No.352,809. It is of such a construction that it may be opened by pressureof the spout of the oil. can, and when the spout is withdrawn, Wlllclose automatically.

The invention will be fully understood from the following descriptionwhen taken in connection with the accompanying drawings, and the novelfeatures will be pointed out and clearly defined in the claims at theclose of this-specification.

In the drawings, Figure 1 is a side elevation of an oil cup to which isapplied a closure embodying my invention. r

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 shows the position occupied by the parts when the spout of theoil can has been inserted.

Referring now to the drawings, the oil cup is indicated at 11. Theclosure embodymg my invention comprises a close-wound spiral spring 12preferably of cylindrical form, one end of which is secured to a flange13 formed on the casing of the oil cup 11 and the other end of which isclosed by a cap 14. Under ordinary conditions, the resiliency of thewire from which the spring is made holds the turns in contact with eachother. I find by experiment that this contact is so close that theresulting structure is practically oil-tight. Furthermore, the contactbetween'the turns of the spring is so close that dust and grit cannotpenetrate. Oil may be inserted by pushing the nose of the oil canagainst the closure. The nose of the oil can can be pushed-between twoadjacent turns of the wire and separates them permitting oil tobe'injected. When the spout of the oil can is withdrawn, the coils snaptogether again, eifectively sealing the oil cup.

This closure is .particularly effective because it cannot be left Openby the user. and neither will it jar open or get opened accidentally. Infact, it is never open except momentarily while the oil is beinginserted. It also makes it possible to perform the work of oiling by theuse of one hand because the oil can, while held in onehand by theoperator, may have its spout pushed against the side of the closure,whereupon the closure opens automatically and will close again after thespout has been removed. In practice a'special oil can having 'a thin orwedge-shaped spout will be employedas this finds its way more readilybetween the Such a spout is shown permit the insertion of the spout ofan oil can between the turns and closing means for the end ofrthespring.

2. In combination withan oil reservoir, a protctive closure for theinlet opening thereof comprising a spiral spring and a' v cap closingthe end of said spring, the

turns of said spring being yieldably separa-' ble from each other topermit the insertion of the spout of an oil can.

In testimony whereof I aflix my signature.

STEPHENLFEKETE.
